By a margin of three percent, Slovenian voters on June 6 approved an agreement on a maritime border dispute with Croatia. Both Croatia and Slovenia wish to resolve an 18-year old dispute over the small Bay of Piran in the Adriatic Sea. In September 2009, the former Yugoslavian nations signed an agreement calling for an international arbitration tribunal to resolve the issue. The Slovenian legislature ratified the 2009 agreement, but pressure from the center-right opposition forced the government to put the issue to referendum. The dispute has damaged relations between both countries, causing Slovenia to block Croatia's bid to join the European Union. Turnout for the referendum was 42 percent.
